A preparation method of a composition for skin repair

Abstract

The invention discloses a preparation method of a composition for skin restoration, which is obtained by homogeneous emulsification of an antibacterial restoration agent, a natural plant extract, an emulsifier and deionized water, wherein the antibacterial restoration agent is firstly prepared by chitosan Sugar and baicalin are used as raw materials, esterified under the catalysis of DMAP / DCC, and baicalin is connected to chitosan molecules in the form of chemical bonds, and the obtained compound A is acylated with formic acid, and two molecules of compound A pass through ‑N=C‑NH‑connected to obtain an antibacterial repair agent; the composition can be used for direct coating on the infected skin surface, or added to cosmetics, cool and comfortable, wherein the antibacterial repair agent can be more absorbed and aggregated Moisture moisturizes and locks the skin. For damaged skin, the antibacterial repair agent can be used as a wound filler to absorb wound exudate, heavy metals and bacteria, etc., to sterilize and remove free radicals, promote wound healing, and achieve rapid skin repair. effect.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a preparation method of a composition for skin repair. Background technique [0002] Skin infection is one of the malignant diseases that seriously affect people's life and health. If it is not taken seriously, some may even be life-threatening. The skin consists of epidermis, dermis, and subcutaneous tissue from outside to inside. The dermis contains nerves and sensory nerve endings such as itching, pain, heat, cold, and touch. Common skin infections are usually wounds or skin lesions caused by bacteria or fungi, such as Staphylococcus aureus infection, various dermatophytes, eczema, etc. Free radical is a general term for a class of atoms, atomic groups or molecules containing unpaired electrons. In pathological conditions, a large number of free radicals produced by the body can damage DNA, which is the main cause of cell apoptosis and necrosis. [0003] Baica...

AI Technical Summary

Problems solved by technology

[0003] Baicalin is a flavonoid compound extracted from the root of Scutellaria baicalensis, which has significant biological activity, antibacterial, diuretic, anti-inflammatory, anti-allergic and antispasmodic effects, and has strong physiological effects such as anti-cancer response , absorb ultraviolet rays, scavenge oxygen free radicals, and inhibit the formation of melanin, so it can be used in both medicine and cosmetics. It is a good functional beauty cosmetic raw material, but the compatibility of baicalin is poor. It is easy to be compatible with other components in cosmetics, and it is difficult for the skin to absorb

[0004] Chitosan has excellent properties such as natural polymer biofunctionality and compatibility, blood compatibility, safety, and microbial degradation. Compatibility
